Northstar HVAC & Refrigeration Inc. is a family-owned company serving Northbrook and the surrounding North Shore communities. We handle furnace repair, AC installation, tune-ups, and everything in between, with straight answers and fair pricing. Because we are based just down the road in Glenview, getting to your home is quick.
Northbrook is known for its large, wooded lots and a housing mix that ranges from 1960s and 70s split-levels, ranches, and colonials to newer high-end custom builds. These older homes often sit on generous footprints with original ductwork that was sized for the way people lived decades ago, which means comfort and efficiency don't always match a modern system.
In many established Northbrook homes we see aging furnaces well past their prime, undersized or leaky ductwork, and uneven temperatures between finished basements and upper levels. Mature trees that shade these properties are great for curb appeal, but they also drop debris that can clog outdoor condenser coils, so seasonal cleaning and tune-ups go a long way here.
We are a family-owned shop, not a high-pressure sales outfit, so when an original furnace is genuinely due for replacement we'll tell you, and when a repair makes more sense we'll tell you that too. Being local in Glenview means we know these North Shore homes and we treat Northbrook neighbors the way we'd want our own family treated.

We service heating and cooling throughout Northbrook, including these areas:
The homes near downtown and Village Green tend to be older and well-established, often with original furnaces and ductwork that benefit from a careful tune-up or upgrade. We help these homeowners keep classic homes comfortable without tearing everything apart.
Techny blends longtime residences with newer development on the east side of Northbrook. Whether your system is decades old or recently built, we handle repairs, maintenance, and installs so your home stays comfortable year-round.
Larger homes on bigger lots around the Sportsman's Country Club area often have more square footage to heat and cool, which puts extra demand on the HVAC system. We make sure furnaces and AC units are properly sized and running efficiently for these spacious properties.
